Design And Research Of Wireless Body Area Network System Based On The Health Monitoring

Since the 21 st century,the world's population aging problem increasingly aggravated,China as a country with the largest population in the world,have also become one of the most serious ageing countries,pay attention to the old people's physical health,has gradually become the topic of focus on the health care field.The emergence of wireless body area network,in order to solve this problem provides a feasible solution,the progress of science and technology in modern society,the mobile communication technology rapid development,the Android system because of its good openness and portability,quickly become the mainstream of intelligent mobile phone system,combined with the new type of portable mobile,smaller volume of multifunctional sensor,make the wireless body area network technological change,rapid development,to better service to human health.This paper designs the "wireless body area network system based on health monitoring",using the current cutting-edge Android smart technology,convenient and easy to use bluetooth communication technology,and a variety of different types of sensors,aims to build a human health monitoring information signs parameters real-time observation system.It used for data collection board signs of sensors to collect the body signs of physical information,using the timer interrupt technology signs and real-time access to information,data sent via bluetooth wireless communication network to the mobile terminal,mobile terminal interface to realize all kinds of signs,according to human information data read convenient user,to provide users with a better health service information.This paper through in-depth study of the existing wireless body domain network technology characteristics and existing problems,and start-up of the bluetooth from more than a master,polling access way of communication,realize the terminal all kinds of signs,according to the information data collection,access and transmission based on the current domain network design principles and implementation requirements,the system scientific classification of information collection,information transformation function,bluetooth communication function,digital information transmission,information display and function of information sharing under,to determine the specific functional division of the system.Finally,the designed system has carried on the experiment test,including signs information acquisition and information data conversion,digital matching bluetooth connection and communication,the underlying information data staging and outgoing,android mobile phone client to establish communication with the underlying connection,access to information,information display and so on various functional modules and system integration,test results is good,shows that this system can achieve perfect various signs information real-time monitoring to the human body.
